I scan my system with maldet and as usual, it will send report to my own email address, but Amavis bans it with action DISCARD(bounce.suppressed). I get this record from the mail.log. It also quarantine it in the directory /var/lib/amavis/virusmails/I/. How do I correct it? My system is ISPConfig 3.1.2, Ubuntu 16.04. Maldetect 1.6.
